Asteroid Schiela

by dadu » Tue Aug 16, 2011 9:40 am
Interest in asteroid Schiela has increased, ever since observations by the University of Arizona's Catalina Sky Survey have revealed that the asteroid is twice as bright as previously thought.
(A) twice as bright as
(B) twice as bright as they
(C) two times as bright than
(D) twice as bright as was
(E) two times as bright than was

Please discuss.

Twice is only used with adverb and is more appropriate in this statement.
So, C and E fails

B, (They) - wrong usage

mixed with A and D, IMO:D

IMO A

(A) twice as bright as => Correct. Here I assume "it was" is understood & hence omitted.
(B) twice as bright as they => they has no referent
(C) two times as bright than => incorrect
(D) twice as bright as was => missing "it" (although I'm not so sure here.)
(E) two times as bright than was => incorrect

Whats is OA? Can an expert please verify my reasoning here?

Thanks...

Tough one between A and D but I would have gone for option D because I thought of maintaining parallelism between simple present and simple past i.e asteroid is // was previously thought.......

Looking for expert comments......

In B , had they been a valid pronoun , would B still have been wrong ?
as they previously thought

Hi,
I am not expert. But, I feel A is incorrect.
Best option would be: asteroid is twice as bright as (people/scientists) previously thought.
So, I guess there needs to be a noun before previously thought.
Coming to D, as the active construction is not there, D gives a passive construction
asteroid is twice as bright as was previously thought (by people/scientists). Removing 'by people/scientists' is not going to be incorrect as it is a passive construction. So, I think answer should be D.
In B , had they been a valid pronoun , would B still have been wrong ?
I guess my post answers this as well. If there is a valid noun before 'previously thought', B will be correct.

Please post the OA.
Cheers!

(B) twice as bright as they

The SC is
that the asteroid is twice as bright as previously thought
if u substitute C
we get
that the asteroid is twice as bright as they previously thought

Doesnt the verb " thought " require an object here because we are comparing the actual size of the asteroid with the size that they previously thought

You mean B right?
B is wrong because 'they' has no referent as one of the posters has already mentioned.

Sorry, I didn't clearly understand your question. I guess you are talking about the ellipsis part?Anyway, the construction is a valid one. You can see Q-13, OG-12 :
A surge in new home sales and a drop in weekly unemployment claims suggest that the economy might not be as weak as some analysts previously thought.
Cheers!

IMO D

I think 'was' is required..
as bright as construction needs to be parallel..

so,
X as bright as Y.. in this X and Y need to be parallel..
X is in present tense (asteroid is) and Y is in past (previously).. so we need 'was' in Y... otherwise, present tense (is) in X would apply to Y as well. We don't want it to happen obviously.

i received a pm.

what is the source of this question? the sentence is very, very badly written; there are at least three things wrong with the non-underlined portion of the sentence.

you should ignore this question, and you should also be extremely suspicious of other questions from the same source.
